Detect at the boundary
Long fence lines need detection and verification before anyone drives out to an unmanned site.
HJ SECURITY · KUCHING & SARAWAK
Security for unmanned substations and utility compounds.
Plan perimeter detection, CCTV, access control and remote monitoring around unmanned sites, long boundaries and the operator's permit-to-work rules. HJ reviews security and ELV requirements for substations and utility compounds across Sarawak.
THE STARTING POINT
Start with the everyday problem.
Control who enters
Staff and contractor entry should follow the permit-to-work process, with records the operator can review.
Keep monitoring running
Remote links, backup power and equipment health have to hold up through outages and bad weather.
SYSTEMS & SCOPE
Connect the right parts of the scope.
Choose the areas that match your priorities, then confirm how they work together. Open a topic for related installation or service information.
Perimeter detection
Fence-line detection, infrared beams or sensor cable chosen for the boundary length, terrain and nuisance-alarm risk.
Electric fence
Energised perimeter fencing with zoned alarms where the boundary and the operator's requirements allow it.
Thermal & long-range CCTV
Thermal and long-range cameras for dark compounds and long fence lines, with verification images on alarm.
CCTV & recording
Coverage of gates, control buildings and yards, with recording sized to the required retention.
Access control
Card, PIN or face access for control rooms and equipment buildings, with an entry record for each person.
Contractor & visitor records
Contractor registration and entry records matched to the permit-to-work arrangement.
Gate & vehicle entry
Motorised gates or barriers with plate capture and remote release where the site requires it.
Gate intercom
Gate and help-point intercoms so visitors and crews can reach the control room.
Multi-site monitoring
One view of alarms, cameras and access events across many unmanned sites.
Site connectivity
Fibre, 4G, wireless or Starlink backhaul selected for each location, with failover where needed.
Backup power
UPS and battery runtime for security equipment, so alarms and recording continue during a supply interruption.
Equipment-room monitoring
Temperature, humidity and water-ingress alerts for equipment rooms and outdoor cabinets.
Solar & 4G cameras
Solar-powered cameras with 4G where a suitable power or network point is not available.
Wireless bridge
Point-to-point links between the gate, control building and camera poles.
Lightning & surge protection
Surge protection and earthing for poles, cameras and network equipment in exposed compounds.

Planning that fits the site.
New site or upgrade programme
- Provide the site plans, boundary lengths and the operator's security specification.
- Confirm permit-to-work, induction and escort requirements before any site visit.
- Agree which alarms, video and records must reach the control room.
Existing sites
- Provide an authorised contact and access arrangements for each site.
- Review existing cameras, fence detection, links and backup power.
- Prioritise sites and agree a rollout sequence.
BEFORE THE QUOTATION
What changes the scope and cost?
Boundary
Fence length, terrain and gate openings.
Remote links
Backhaul, failover and the monitoring centre.
Site rules
Permits, escorts and work windows.
Sites
Number of sites and the rollout sequence.
USEFUL ANSWERS
Questions before you start.
Does HJ work on high-voltage equipment?
No. HJ's scope is security and ELV systems. Any work in or near energised equipment follows the operator's permit-to-work, safety clearance and supervision rules, and the high-voltage equipment itself stays outside HJ's scope.
Can alarms from many unmanned substations go to one control room?
Yes, where the links and the monitoring platform allow it. Event types, video verification and who responds are agreed for each site before alarms are routed.
What happens when the power or the link goes down?
Backup power and failover links are sized for the agreed runtime, and the system can raise a power-fail or link-loss alarm so the operator knows a site is offline.
Can existing fence detection or cameras be reused?
The assessment checks condition and compatibility first. Equipment is retained where it meets the agreed requirements.
